[0020] To make the purpose, technical scheme and advantages of the present application clearer, the present application will be further described in detail below with reference to the drawings. It is hereby declared that the up, down, left, right, front, back, inner and outer directions appearing or about to appear in the present application in the text are based on the drawings of the present application, and are not specific limitations on the present application.

[0021] As shown in Fig. 1, the present application provides a hydrogen production and hydrogen dissolving control method, comprising:

[0022] S101, controlling the electrolytic cell to perform electrolysis of water;

[0023] Specifically, the step of controlling the electrolytic cell to perform electrolysis of water further comprises:

[0024] Step 1, acquiring a first water level signal detected by a first water level detection sensor in the water tank in real time;

[0025] Step 2, when the first water level signal reaches a first preset water level threshold, controlling a first water pump of the water tank to supply water to the heat exchange pipeline of the water chiller;

[0026] Step 3, acquiring a first water temperature signal detected by a first temperature sensor in the heat exchange pipeline in real time;

[0027] Step 4, when the first water temperature signal meets a first preset temperature threshold range, controlling a second water pump of the water chiller to supply water to the electrolytic cell, otherwise controlling the water chiller to perform water temperature adjustment work.

[0028] It should be noted that before electrolyzing water, the first water level signal in the water tank is detected by the first water level detection sensor in the water tank; when the first water level signal reaches the first preset water level threshold, it indicates that the water in the water tank is sufficient for water supply, and at this time the first water pump is controlled to supply water to the heat exchange pipeline of the water chiller.

[0029] In order to improve the electrolysis efficiency, the water supplied to the electrolytic cell needs to be treated, and specifically the working water temperature needs to be controlled. The first water temperature signal in the heat exchange pipeline is detected by the first temperature sensor, and when the first water temperature signal meets the first preset temperature threshold range, it indicates that the water temperature has reached the required working water temperature range, and at this time the second water pump is controlled to supply water to the electrolytic cell to improve the electrolysis efficiency; when the first water temperature signal does not meet the first preset temperature threshold range, the water temperature in the heat exchange pipeline is adjusted by controlling the water chiller, so that the water temperature meets the preset temperature threshold range, and then the second water pump is controlled to work to provide water with suitable temperature for the electrolytic cell, and finally the electrolytic water work is carried out by the electrolytic cell to obtain the required hydrogen.

[0030] Preferably, the first preset temperature threshold range is preferably 20-28°C, but is not limited thereto, and can be adjusted according to actual needs.

[0031] S102, controlling the separation and purification mechanism to carry out gas-liquid separation and hydrogen purification on the hydrogen obtained by the electrolytic cell to obtain purified hydrogen;

[0032] Specifically, the separation and purification mechanism includes a gas-liquid separator, a heating device, a purifier and a cooling bin, and the step of controlling the separation and purification mechanism to carry out gas-liquid separation and hydrogen purification on the hydrogen obtained by the electrolytic cell to obtain purified hydrogen includes:

[0033] Step 1, controlling the cold water flow valve of the gas-liquid separator to open, so that the cold water in the water chiller circulates in the gas-liquid separator;

[0034] It should be noted that when the electrolytic cell produces hydrogen, the hydrogen flows into the separation zone in the gas-liquid separator, and at this time the cold water flow valve is controlled to open, so that the cold water of the water chiller circulates in the cooling zone of the gas-liquid separator, and the separation zone in the cooling zone is cooled by the cold water in the cooling zone, so that the water mixed in the hydrogen is condensed into liquid, realizing gas-liquid separation. The cold water flow valve includes a cold water input valve and a cold water output valve, and the cold water input valve and the cold water output valve are in communication with the water chiller.

[0035] Step 2, real-time acquisition of the second water level signal detected by the second water level detection sensor in the gas-liquid separator;

[0036] Step 3, when the second water level signal reaches the second preset water level threshold, the drain valve of the gas-liquid separator is controlled to open to drain the liquid separated by the gas-liquid separator into the water tank;

[0037] It should be noted that as the gas-liquid separator separates, the condensed liquid in the separation zone gradually accumulates, and when the accumulated liquid exceeds the preset water level, the second water level detection sensor will detect the corresponding second water level signal, at which time the drain valve of the gas-liquid separator is controlled to open to drain the separated liquid back to the water tank, realizing the recycling of water, and the separated dry hydrogen gas flows to the purifier through the gas outlet.

[0038] Step 4, the heating device is controlled to maintain the purification temperature of the purifier within a second preset temperature threshold range, so that the separated hydrogen gas is rapidly purified by the purifier under the preset temperature state;

[0039] Specifically, the step of controlling the heating device to maintain the purification temperature of the purifier within a second preset temperature threshold range, so that the separated hydrogen gas is rapidly purified by the purifier under the preset temperature state, comprises:

[0040] Step 4.1, control the heating device to heat the purifier;

[0041] It should be noted that in order to provide hydrogen purification efficiency, when the electrolysis water is working, the heating device is controlled to heat the purifier in advance, so that the purifier enters the best purification state as soon as possible for work.

[0042] Step 4.2, real-time acquisition of the second temperature signal detected by the second temperature sensor in the purifier;

[0043] Step 4.3, when the second temperature signal meets the second preset temperature threshold range, the inlet valve of the purifier is controlled to open and the heating device is controlled to maintain the purification temperature of the purifier within a second preset temperature threshold range, so that the separated hydrogen gas is rapidly purified by the purifier under the preset temperature state.

[0044] It should be noted that when the second temperature signal detected by the second temperature sensor meets the second preset temperature threshold range, the inlet valve of the purifier is controlled to open and the heating device is controlled to continue to maintain the purification temperature of the purifier within the second preset temperature threshold range, and the rapid purification work is carried out through the purifier at the purification temperature. Specifically, the purifier is filled with specific adsorbents, which have the ability to selectively adsorb impurities in hydrogen. When hydrogen containing impurities enters the purifier, under a certain pressure, the adsorbents will adsorb the impurity molecules such as water, oxygen and other gas components in the hydrogen, and the hydrogen molecules will pass through the adsorption layer due to their small molecular size and weak interaction with the adsorbents, thereby realizing the purification of hydrogen. At the same time, the purifier at the current purification temperature utilizes the differences in diffusion rate, adsorption characteristics and other differences between hydrogen and other substances to remove impurities such as water vapor, oxygen, carbon dioxide and chlorine in hydrogen, so as to further purify hydrogen. The purified hydrogen can improve the purity of the hydrogen dissolving, thereby improving the efficiency of the hydrogen dissolving. The second preset temperature threshold range is preferably 95-105°C, but is not limited thereto, and can be adjusted according to actual needs.

[0045] Step 5, control the cooling valve of the cooling bin to open, so that the cold water in the water chiller flows through the cooling bin in the separation and purification mechanism, and the purified hydrogen is cooled and transported to the supercharger through the cooling bin.

[0046] It should be noted that in order to control the temperature of hydrogen within a preferred range before dissolving, the cooling valve of the cooling bin is controlled to open, so that the cold water in the water chiller flows through the cooling bin in the separation and purification mechanism, and the hydrogen is cooled by the cooling bin. After being cooled to a cooling preset temperature, the hydrogen is introduced into the supercharger. The cooling valve includes a cooling input valve and a cooling output valve.

[0047] Further, the step of rapidly purifying the separated hydrogen further comprises: acquiring a hydrogen flow signal detected by a gas flow meter in the output pipeline of the purifier in real time; controlling the pressure regulating valve in the output pipeline to adjust the flow until the hydrogen flow signal meets the preset flow threshold range; when the hydrogen flow signal meets the preset flow threshold range, the cooling valve and the supercharger are started to work.

[0048] It should be noted that in order to improve the hydrogen dissolving efficiency and the hydrogen dissolving content, hydrogen gas with a certain flow rate is required to carry out the hydrogen dissolving work by using high content hydrogen gas as raw material. In this regard, the hydrogen flow signal is detected in real time by the gas flow meter, and at the same time the pressure regulating valve in the output pipeline is controlled to adjust the flow rate until the hydrogen flow signal meets the preset flow rate threshold range. When the hydrogen flow signal meets the preset flow rate threshold range, the cooling valve and the supercharger are started to work to output hydrogen gas with a corresponding flow rate to the subsequent cooling valve and supercharger, thereby improving the subsequent hydrogen dissolving efficiency and hydrogen dissolving content. The preset flow rate threshold range can be set according to the actual situation of the user, and is not limited here.

[0049] Further, precision filters are arranged between the gas-liquid separator and the purifier and between the purifier and the cooling bin. Generally, hydrogen gas produced by electrolysis of water may contain some impurities or particles, which may affect the purity and stability of hydrogen gas, and even may cause damage to the equipment. The precision filter can effectively trap these impurities and particles inside the filter by its designed microporous or filter medium, so that the hydrogen gas treated by the filter is more pure, which can protect the purifier and the cooling bin, and also helps to improve the purity of hydrogen gas.

[0050] S103、control the supercharger to perform pressure boosting treatment on the purified hydrogen gas and input it into the reaction tank;

[0051] S104、real-time acquisition of the pressure signal in the reaction tank detected by the pressure sensor;

[0052] S105、when the pressure signal meets the preset pressure threshold range, control the ultrasonic generator in the reaction tank to perform hydrogen dissolving work and timing, and when the hydrogen dissolving work time is equal to the preset work threshold, control the ultrasonic generator and the supercharger to stop working.

[0053] Specifically, when the pressure signal meets the preset pressure threshold range, the step of controlling the ultrasonic generator in the reaction tank to perform hydrogen dissolving work includes:

[0054] Step 1, when the pressure signal meets the preset pressure threshold range, control the supercharger to perform pressure maintaining work and perform pressure maintaining timing;

[0055] Step 2, when the pressure maintaining time is equal to the preset pressure maintaining time threshold and the pressure signal within the pressure maintaining time meets the preset pressure threshold range, control the ultrasonic generator in the reaction tank to perform hydrogen dissolving work.

[0056] It should be noted that the hydrogen is pressurized by the booster, and the pressurized hydrogen enters the reaction tank to realize hydrogen supply and pressurization of the reaction tank. The pressure sensor arranged on the reaction tank detects the pressure signal in the reaction tank in real time. When the pressure signal in the reaction tank meets the preset pressure threshold range, the booster is controlled to perform pressure maintaining work and pressure maintaining timing to ensure that the current high-pressure environment is stable. When the pressure maintaining time is equal to the preset pressure maintaining time threshold and the pressure signal in the pressure maintaining time meets the preset pressure threshold range, it is indicated that the reaction tank is in a stable high-pressure environment. At this time, the ultrasonic generator in the reaction tank is controlled to perform hydrogen dissolving work and timing. When the hydrogen dissolving work time is equal to the preset work threshold, the ultrasonic generator and the booster are controlled to stop working. Under the ultrasonic wave vibration generated by the ultrasonic generator, hydrogen is quickly dissolved in water in the high-pressure container to realize rapid hydrogen dissolving work, and the hydrogen dissolving efficiency and hydrogen dissolving content are high, which effectively meets the high-standard use demand of the user. The preset work threshold can be adjusted according to the actual demand of the user, which is not limited here.

[0057] Preferably, the ultrasonic generator is arranged at the bottom of the reaction tank, the generated ultrasonic wave can be more uniformly propagated and cover the whole solution, and it is also helpful to prevent hydrogen bubbles from gathering at the bottom and reduce the formation of bubble groups, so that the effect of bubble groups on hydrogen dissolving can be avoided, and the hydrogen dissolving efficiency and hydrogen dissolving content are improved.

[0058] Preferably, the preset pressure threshold range is preferably 1.5-2.5 MPa, but is not limited to this, and can be adjusted according to the actual demand.

[0059] Further, the step of controlling the ultrasonic generator and the booster to stop working when the hydrogen dissolving work time is equal to the preset work threshold further comprises: waiting timing; when the waiting time is equal to the preset waiting time threshold, the pressure relief valve of the reaction tank is controlled to perform pressure relief treatment.

[0060] It should be noted that after the ultrasonic generator and the booster are controlled to stop working, waiting timing is performed to make more hydrogen stably dissolve into water, so that the hydrogen dissolving effect of the prepared hydrogen-rich water tends to be stable. When the waiting time is equal to the preset waiting time threshold, it is indicated that the hydrogen dissolving effect is stable, and at this time, the pressure relief valve of the reaction tank is controlled to perform pressure relief treatment to discharge excess hydrogen, thereby ensuring the safety of the system.

[0061] Preferably, the multiple reaction tanks can be pressurized one by one to ensure the safety of the operation process, since the material, structure and sealing performance of each reaction tank can be different, and the pressurization can cause the internal pressure of the reaction tank to rise rapidly, if all the reaction tanks are pressurized at the same time, once an abnormal situation occurs, such as leakage or rupture of a reaction tank, a chain reaction can be triggered, increasing the risk of accidents, and pressurizing one by one can discover and handle potential safety hazards in time, ensuring the safe and stable operation of each reaction tank. Secondly, pressurizing one by one is conducive to realizing accurate control of the hydrogen dissolution process in each reaction tank. The volume, shape and internal hydrogen and water mixing of different reaction tanks can be different, which will affect the dissolution efficiency of hydrogen. By pressurizing one by one, the pressurization rate and pressure level can be adjusted according to the actual situation of each reaction tank, and the reaction pressure preset value and reaction time preset value of each reaction tank can be set separately, to ensure that hydrogen can be fully dissolved in each reaction tank, thereby improving the hydrogen dissolution efficiency and hydrogen utilization rate.

[0062] Before the current reaction tank completes pressurization, pressure maintenance and pressure relief, the electromagnetic valves corresponding to other reaction tanks are closed to prevent hydrogen from entering other reaction tanks; after the current reaction tank completes pressurization, pressure maintenance and pressure relief, the electromagnetic valve corresponding to the reaction tank is closed, and the electromagnetic valve corresponding to the next reaction tank is opened, to prevent the pressure relief operation of the previous reaction tank from affecting the next reaction tank, so that the pressure relief operation of the previous reaction tank and the pressurization operation of the next reaction tank can be carried out at the same time, improving the overall operation efficiency.

[0063] As shown in FIGS. 2-3, the application also provides a hydrogen production and dissolution control system, which comprises a hydrogen production and dissolution controller 1 and a water tank 2, a water chiller unit 3, an electrolytic tank 4, a separation and purification mechanism 5, a pressure booster 6 and a reaction tank 7 connected in sequence. The reaction tank 7 is provided with a pressure sensor 71 and an ultrasonic generator 72, and the hydrogen production and dissolution controller 1 is provided to control the operation of each electronic device to realize the function of hydrogen production and dissolution. The hydrogen production and dissolution controller 1 comprises:

[0064] A hydrogen production processing module 11 is used to control the electrolytic tank 4 to perform electrolysis of water;

[0065] Specifically, before the control electrolytic cell 4 performs the water electrolysis work, the hydrogen production processing module is further used for: acquiring a first water level signal detected by a first water level detection sensor 21 in the water tank 2 in real time; when the first water level signal reaches a first preset water level threshold, controlling the first water pump 22 of the water tank 2 to supply water to the heat exchange pipeline of the water chiller 3; acquiring a first water temperature signal detected by a first temperature sensor in the heat exchange pipeline in real time; when the first water temperature signal meets a first preset temperature threshold range, controlling the second water pump 31 of the water chiller 3 to supply water to the electrolytic cell 4, otherwise controlling the water chiller 3 to perform water temperature adjustment work.

[0066] It should be noted that before the water electrolysis work is performed, the first water level signal in the water tank 2 needs to be detected by the first water level detection sensor 21 in the water tank 2; when the first water level signal reaches the first preset water level threshold, it indicates that the water quantity in the water tank 2 is sufficient for water supply at present, and at this time the first water pump 22 is controlled to supply water to the heat exchange pipeline of the water chiller 3.

[0067] In order to improve the electrolysis efficiency, the water supplied into the electrolytic cell 4 needs to be treated, and specifically the working water temperature needs to be controlled. The first water temperature signal in the heat exchange pipeline is detected by the first temperature sensor, and when the first water temperature signal meets the first preset temperature threshold range, it indicates that the water temperature has reached the required working water temperature range, at this time the second water pump 31 is controlled to supply water to the electrolytic cell 4, so as to improve the electrolysis efficiency; when the first water temperature signal does not meet the first preset temperature threshold range, the water temperature in the heat exchange pipeline is adjusted by controlling the water chiller 3, so that the water temperature meets the preset temperature threshold range, and then the second water pump 31 is controlled to work, to provide water with suitable temperature for the electrolytic cell 4, and finally the water electrolysis work is performed by the electrolytic cell 4 to obtain the required hydrogen.

[0068] Preferably, the first preset temperature threshold range is preferably 20-28℃, but is not limited thereto, and can be adjusted according to actual needs.

[0069] The separation and purification processing module 12 is used for controlling the separation and purification mechanism 5 to perform gas-liquid separation and hydrogen purification on the hydrogen produced by the electrolytic cell 4, so as to obtain purified hydrogen.

[0070] Specifically, the separation and purification mechanism 5 includes a gas-liquid separator 51, a heating device 52, a purifier 53 and a cooling bin 54, and the separation and purification processing module 12 is specifically used for the following control work:

[0071] The cold water flow valve of the gas-liquid separator 51 is controlled to be opened, so that the cold water in the cold water unit 3 flows in the gas-liquid separator 51; it should be noted that when the electrolytic cell 4 produces hydrogen, the hydrogen will flow to the separation area in the gas-liquid separator 51, at this time, the cold water flow valve is controlled to be opened, so that the cold water of the cold water unit 3 circulates in the cooling area of the gas-liquid separator 51, and the separation area in the cooling area is cooled by the cold water in the cooling area, so that the water mixed in the hydrogen is condensed into liquid, and the gas-liquid separation work is realized. The cold water flow valve includes a cold water input valve 511 and a cold water output valve 512, and the cold water input valve 511 and the cold water output valve 512 are respectively communicated with the cold water unit 3.

[0072] The second water level signal detected by the second water level detection sensor 513 in the gas-liquid separator 51 is acquired in real time; when the second water level signal reaches the second preset water level threshold, the drain valve 514 of the gas-liquid separator 51 is controlled to be opened, so that the liquid separated by the gas-liquid separator 51 is drained into the water tank 2; it should be noted that as the gas-liquid separator 51 performs the separation work, the liquid condensed in the separation area gradually accumulates, when the accumulated liquid exceeds the preset water level, the second water level detection sensor 513 will detect the corresponding second water level signal, at this time, the drain valve 514 of the gas-liquid separator 51 is controlled to be opened, so that the separated liquid is drained back to the water tank 2, realizing the recycling of water, and the separated dry hydrogen flows to the purifier 53 through the gas outlet.

[0073] The heating device 52 is controlled to maintain the purification temperature of the purifier 53 within the second preset temperature threshold range, so that the separated hydrogen is rapidly purified by the purifier 53 under the preset temperature state;

[0074] Specifically, the content that the control heating device 52 maintains the purification temperature of the purifier 53 within the second preset temperature threshold range, so that the separated hydrogen is rapidly purified by the purifier 53 under the preset temperature state includes:

[0075] The heating device 52 is controlled to heat the purifier 53; it should be noted that in order to provide hydrogen purification efficiency, when the electrolytic water works, the heating device 52 is controlled to heat the purifier 53 in advance, so that the purifier 53 enters the best purification state as soon as possible to work.

[0076] The second temperature signal detected by the second temperature sensor in the purifier 53 is acquired in real time; when the second temperature signal meets the second preset temperature threshold range, the air inlet valve of the purifier 53 is controlled to open, and the heating device 52 is controlled to maintain the purification temperature of the purifier 53 within the second preset temperature threshold range, so that the separated hydrogen is rapidly purified by the purifier 53 under the preset temperature state. It should be noted that when the second temperature signal detected by the second temperature sensor meets the second preset temperature threshold range, the air inlet valve of the purifier 53 is controlled to open, and the heating device 52 is controlled to continue to maintain the purification temperature of the purifier 53 within the second preset temperature threshold range, so that the hydrogen is rapidly purified by the purifier 53 under the purification temperature. Specifically, the purifier 53 is filled with specific adsorbents, which have the ability to selectively adsorb impurities in hydrogen. When hydrogen containing impurities enters the purifier 53, under a certain pressure, the adsorbents will adsorb the impurity molecules in the hydrogen, such as water, oxygen and other gas components, while the hydrogen molecules will pass through the adsorption layer due to their smaller molecular size and weaker interaction with the adsorbents, thereby achieving purification of hydrogen. At the same time, the purifier 53 under the current purification temperature utilizes the differences in diffusion rate, adsorption characteristics, etc. between hydrogen and other substances to remove impurities such as water vapor, oxygen, carbon dioxide, chlorine, etc. contained in hydrogen, so as to further purify hydrogen. The purified hydrogen can improve the purity of hydrogen dissolution, thereby improving the efficiency of hydrogen dissolution. The second preset temperature threshold range is preferably 95-105°C, but is not limited thereto and can be adjusted according to actual needs.

[0077] The cooling valve of the cooling bin 54 is controlled to open, so that the cold water in the water chiller 3 flows through the cooling bin 54 in the separation and purification mechanism 5, and the purified hydrogen is cooled by the cooling bin 54 and delivered to the booster 6. It should be noted that in order to control the temperature of hydrogen within a preferable range before dissolution, the cooling valve of the cooling bin 54 is controlled to open, so that the cold water in the water chiller 3 flows through the cooling bin 54 in the separation and purification mechanism 5, and the hydrogen is cooled by the cooling bin 54. After being cooled to a preset cooling temperature, the hydrogen is introduced into the booster 6. The cooling valve includes a cooling input valve 541 and a cooling output valve 542.

[0078] Further, the content of rapidly purifying the separated hydrogen also includes: acquiring the hydrogen flow signal detected by the gas flow meter 531 in the output pipeline of the purifier 53 in real time; controlling the pressure regulating valve 532 in the output pipeline to perform flow adjustment until the hydrogen flow signal meets the preset flow threshold range; when the hydrogen flow signal meets the preset flow threshold range, the cooling valve and the booster 6 are started to work.

[0079] It should be noted that in order to improve the hydrogen dissolving efficiency and hydrogen dissolving content, hydrogen gas with a certain flow rate is required to carry out hydrogen dissolving work by using high content hydrogen gas as raw material. For this purpose, the hydrogen flow signal is detected in real time by the gas flow meter 531, and at the same time the pressure regulating valve 532 in the output pipeline is controlled to carry out flow adjustment work until the hydrogen flow signal meets the preset flow threshold range. When the hydrogen flow signal meets the preset flow threshold range, the cooling valve and the supercharger 6 are started to work to output hydrogen gas with a corresponding flow rate to the subsequent cooling valve and supercharger 6, thereby improving the subsequent hydrogen dissolving efficiency and hydrogen dissolving content. The preset flow threshold range can be set according to the actual situation of the user, and is not limited here.

[0080] Further, precision filters 8 are provided between the gas-liquid separator 51 and the purifier 53 and between the purifier 53 and the cooling bin 54. Generally, hydrogen gas produced by electrolysis of water may contain some impurities or particles, which may affect the purity and stability of hydrogen gas, and even may cause damage to the equipment. The precision filters 8 can effectively trap these impurities and particles inside the filter by the design of micropores or filter medium, so that the hydrogen gas treated by the filter is more pure, which can protect the purifier 53 and the cooling bin 54, and also helps to improve the purity of hydrogen gas.

[0081] The supercharging processing module 13 is used to control the supercharger 6 to carry out supercharging processing on the purified hydrogen gas and input it into the reaction tank 7. The acquisition module 14 is used to acquire the pressure signal in the reaction tank 7 detected by the pressure sensor 71 in real time. The hydrogen dissolving processing module 15 is used to control the ultrasonic generator 72 in the reaction tank 7 to carry out hydrogen dissolving work when the pressure signal meets the preset pressure threshold range, and to count the time. When the hydrogen dissolving work time is equal to the preset work threshold value, the ultrasonic generator 72 and the supercharger 6 are controlled to stop working.

[0082] Specifically, when the pressure signal meets the preset pressure threshold range, the supercharger 6 is controlled to carry out pressure maintaining work and pressure maintaining timing. When the pressure maintaining time is equal to the preset pressure maintaining time threshold value and the pressure signal in the pressure maintaining time meets the preset pressure threshold range, the ultrasonic generator 72 in the reaction tank 7 is controlled to carry out hydrogen dissolving work.

[0083] It should be noted that the hydrogen is pressurized by the booster 6, so that the pressurized hydrogen enters the reaction tank 7 to realize the hydrogen supply and pressurization of the reaction tank 7. The pressure sensor 71 arranged on the reaction tank 7 detects the pressure signal in the reaction tank 7 in real time. When the pressure signal in the reaction tank 7 meets the preset pressure threshold range, the booster 6 is controlled to perform pressure maintaining work and pressure maintaining timing to ensure the stability of the current high pressure environment. When the pressure maintaining time is equal to the preset pressure maintaining time threshold and the pressure signal in the pressure maintaining time meets the preset pressure threshold range, it is indicated that the reaction tank 7 is in a stable high pressure environment. At this time, the ultrasonic generator 72 in the reaction tank 7 is controlled to perform hydrogen dissolving work and timing. When the hydrogen dissolving work time is equal to the preset work threshold, the ultrasonic generator 72 and the booster 6 are controlled to stop working. Under the ultrasonic wave vibration generated by the ultrasonic generator 72, the hydrogen is quickly dissolved in water in the high pressure container to realize the rapid hydrogen dissolving work, and the hydrogen dissolving efficiency and hydrogen dissolving content are high, which effectively meets the high standard use demand of the user. The preset work threshold can be adjusted according to the actual demand of the user, which is not limited here.

[0084] Preferably, the ultrasonic generator 72 is arranged at the bottom of the reaction tank 7, the generated ultrasonic wave can be more uniformly propagated and cover the whole solution, and it is also helpful to prevent hydrogen bubbles from gathering at the bottom and reduce the formation of bubble groups, so that the effect of bubble groups on hydrogen dissolving can be avoided, and the hydrogen dissolving efficiency and hydrogen dissolving content are improved.

[0085] Preferably, the preset pressure threshold range is preferably 1.5-2.5 MPa, but is not limited to this, and can be adjusted according to the actual demand.

[0086] Further, when the hydrogen dissolving work time is equal to the preset work threshold, the ultrasonic generator 72 and the booster 6 are controlled to stop working, which further includes waiting timing; when the waiting time is equal to the preset waiting time threshold, the pressure relief valve 73 of the reaction tank 7 is controlled to perform pressure relief treatment.

[0087] It should be noted that after the ultrasonic generator 72 and the booster 6 are controlled to stop working, the waiting timing is performed to make more hydrogen stably dissolve into water, so that the hydrogen dissolving effect of the prepared hydrogen-rich water tends to be stable. When the waiting time is equal to the preset waiting time threshold, it is indicated that the hydrogen dissolving effect is stable, and at this time the pressure relief valve 73 of the reaction tank 7 is controlled to perform pressure relief treatment to discharge the excess hydrogen, thereby ensuring the safety of the system.

[0088] Preferably, the plurality of reaction tanks 7 can be pressurized one by one to ensure the safety of the operation process, because there may be differences in the material, structure and sealing performance of each of the reaction tanks 7, and the pressurization may cause the pressure inside the reaction tank 7 to rise rapidly, and if all the reaction tanks 7 are pressurized at the same time, once an abnormal situation occurs, such as leakage or rupture of a certain reaction tank 7, a chain reaction may be triggered, increasing the risk of accidents, and pressurizing one by one can timely discover and handle potential safety hazards, ensuring the safe and stable operation of each of the reaction tanks 7. Secondly, pressurizing one by one is conducive to realizing precise control of the hydrogen dissolution process in each of the reaction tanks 7, because the volume, shape and internal hydrogen and water mixing conditions of different reaction tanks 7 may be different, which will affect the hydrogen dissolution efficiency, and by pressurizing one by one, the pressurization rate and pressure level can be adjusted according to the actual situation of each of the reaction tanks 7, and the reaction pressure preset value and reaction time preset value of each of the reaction tanks 7 can be set individually, to ensure that hydrogen can be fully dissolved in each of the reaction tanks 7, thereby improving the hydrogen dissolution efficiency and hydrogen utilization rate.

[0089] Before the current reaction tank 7 completes pressurization, pressure maintenance and pressure relief, the solenoid valve 74 corresponding to other reaction tanks 7 is closed to prevent hydrogen from entering other reaction tanks 7; after the current reaction tank 7 completes pressurization, pressure maintenance and pressure relief, the solenoid valve 74 corresponding to the reaction tank 7 is closed, and the solenoid valve 74 corresponding to the next reaction tank 7 is opened, to prevent the pressure relief operation of the previous reaction tank 7 from affecting the next reaction tank 7, so that the pressure relief operation of the previous reaction tank 7 and the pressurization operation of the next reaction tank 7 can be performed at the same time, improving the overall operation efficiency.

[0090] The application further provides a computer device, including a memory, a processor and a computer program stored in the memory and executable on the processor, wherein the processor implements the steps of the above method when executing the computer program.

[0091] The application further provides a storage medium storing a computer program, wherein the computer program is executable on a processor to implement the steps of the above method.

[0092] In summary, the application can separate and purify hydrogen obtained by electrolysis to obtain high-purity hydrogen after drying and removing impurities, and can construct a high-pressure hydrogen dissolution environment in the reaction tank and perform hydrogen dissolution on hydrogen in the high-pressure environment through ultrasonic vibration to promote rapid dissolution of hydrogen in pure water in the hydrogen dissolution tank, realize rapid hydrogen dissolution, and improve hydrogen dissolution efficiency and hydrogen dissolution content, effectively meeting the high-standard use requirements of users.

[0093] The above merely provides the preferred embodiment of the present application, and cannot allude the protection scope of the present application, therefore, any equivalent changes made according to the claims of the present application shall be covered by the scope of the present application.
